TN100-IR Portable Turbidimeter (waterproof)

The microprocessor-based waterproof TN100 meter is an easy-to-use turbidimeter that meets the rigour of rugged field applications. It is a “must -have” for anyone monitoring turbidity on the go.

Using an Infrared light source, it delivers laboratory accuracy with a resolution of 0.01 NTU across an extended range of up to 20 NTU (Nephelometric Turbidity Units).

Details:

  • IP67 Waterproof and Dustproof – Cleaning and maintenance is simple. It floats!
  • Automatic Push-Button Calibration (4 points) for unprecedented full-range accuracy
  • Sturdy Carrying Kit complete with 4 calibration standards, 3 empty cuvettes, batteries and comprehensive instruction manual
  • Power-saving feature allows over 1200 measurements to be taken with a single set of AAA alkaline batteries
  • Large Easy-to-Read Display for optimum viewing of measurements with user-friendly message codes for easy troubleshooting
  • Meets Performance Criteria as specified by ISO 1727 (DIN EN 27027) method
